What is the difference between the Austin Air HealthMate and the Austin Air HealthMate Plus?
Both have a True Medical HEPA filter and granular carbon and zeolite. The carbon in the Plus model however, has the added benefit of impregnated potassium iodide. This makes the unit even more effective at removing formaldehyde and ammonia. The Austin Air HealthMate Plus is best used in places like new homes, laboratories, beauty salons, funeral homes, etc. Sources of formaldehyde in homes can be carpets, wood panel, construction materials and furniture upholstery.
